Definitions
- the product polyethylene polymer and copolymers have a density of about 0.91 to 0.97, molecular weight of about 500 to 900,000 grams/mole, a very low level of fines, uniform spherical particles, very good thermal stability and excellent optical properties.
- heterogeneous metallocene-based catalysts intrinsically possess high activity, though the catalyst precursors and, in particular the cocatalysts required for polymerization, such as aluminoxanes or borane compounds, are very expensive and troublesome in use. Further, another limitation that both catalyst systems share is the lengthy method of preparation and relatively high levels of fines generated in the polymers.
- U.S. Patent 4,173,547 to Graff describes a supported catalyst prepared by treating a support, for example silica, with both an organoaluminum and an organomagnesium compound. The treated support was then contacted with a tetravalent titanium compound.
- U.S. Patent No. 3,787,384 to Stevens et al. discloses a catalyst prepared by first reacting a silica support with a Grignard reagent and then combining the mixture with a tetravalent titanium compound.
- the active catalyst components were deposited on the polymeric support by physical impregnation.
- Other physical impregnation methods include those described in U.S. Pat. No. 4,568,730 to Graves whereby polymer resins of styrene-divinylbenzene are partially softened and the active catalyst components are homogeneously mixed in the resin to form a mass, which was subsequently pelletized or extruded into catalyst particles.
- the activity of the above- described polymer supported catalysts is not higher than that of metal oxide supported Ziegler-Natta catalysts.
- Polypropylene and polyethylene have also found use as polymeric supports, where the polymeric material is typically ground with the catalyst components, which represents a difficult and complicated catalyst preparation procedure.
- the support material there remains a significant concern as to the ability of the support material to retain the active species, deposited by physical impregnation, during polymerization conditions and thus generate, for example, fines.
- Hsu et al, Journal of Polymer Science: Part A: Polymer Chemistry, Vol. 32,2135 (1994) have used poly(ethylene-co-acrylic acid) as a support for Ziegler-Natta catalysts and the catalyst activity was found to be similar to that of the magnesium chloride supported catalyst.
